If the idea of talking to the camera at the back of your iPhone and then turning your iPhone as soon as you’ve spoken to see the person you’re talking to, sounds cool to you, then you might be glad to know that Fring has just enabled video calling and VoIP through 3G on their iPhone app.

Actually, this was a result of the recent announcement made by Apple opening the iPhone’s gates to VoIP calling. Interestingly, Apple made this decision even if it will affect AT&T’s revenues.

To make free voice or video calls using Fring, you simply need to fire up your Fring iPhone app and hope that the message “voip calls are not allowed…” does not appear anymore. If it does, just click “more”, then “go offline” and then open Fring again.

Meanwhile, Fring was not the first iPhone app developer who immediately took advantage of iPhone’s decision to allow VoIP calls on the iPhone. A few days ago, iCall also went live, allowing free VoIP calls for iPhone users through 3G.

Both Fring and iCall if embraced by mobile phone users would definitely make Â the Â VoIP through 3G market more exciting. Expect more mobile apps that will allow VoIP through 3G to be developed and hope that mobile carriers will not disallow this feature even if it affects part of their revenues.
